Bush, left, and Australia's Prime Minister John Howard leave a restaurant after having dinner together in Ho Chi Minh City, Vietnam, in this Sunday, Nov. 19, 2006 file photo. Prime Minister John Howard's big moment in the spotlight may be his swan song. Howard hosts his country's largest-ever gathering of world leaders this week, the annual Asia Pacific Economic Cooperation summit. Soon after, he is expected to call general elections that opinion polls have been saying for months he is going to lose.
